"Explain why you're holding forensic material without an escort, Doctor," Vochak said, his voice flat as hammered lead. Kraynik did not drop the crimson scrap. The physician adjusted the gold-braided collar of his high-tier coat, lifting his chin so his sharp profile caught the low chandelier light. "I run Volkhov Sanatorium, Commander. The Magistrate Council granted me plenary jurisdiction over biological contaminants in the Obsidian Spire three hours ago. If anything here carries neural pathogen residue, it belongs in my quarantine tubes, not in the hands of an unstable field officer." Vochak took two paces forward. He did not shout. He did not draw the heavy iron-pattern sidearm holstered at his ribcage. He simply reached out and gripped the physician's lapels, yanking the older man downward until their foreheads nearly met. "The Council answers to the Iron Garrison when breach protocols are active," Vochak murmured, each syllable scraping against raw gravel. "You breached a sealed crime scene. You touched evidence belonging to the Hunt. Give me that cloth." The physician's mouth pinched, but his grip loosened. The scrap of scarlet silk fluttered into Vochak's waiting palm. Vochak ignored the silk. He shoved the man back against a lacquered table, sending an empty crystal decanter rolling off the edge. It shattered across the parquet floor with a brittle crack. "Clearance revoked," Vochak rasped. "Your access badges for the upper spires are dead as of ten seconds ago. Get out before I decide you're an accomplice." The doctor's neck flushed dark purple. He glanced sideways, his glare landing on Liskra like an iron weight. "You brought this little Coffin Ward scrub to inspect a Tier-One suite? She couldn't diagnose a ruptured spleen without wetting her apron! She stammers if a patient frowns at her!" Liskra shrank into the collar of her frayed grey smock. Her fingernails bit into the calluses of her palms. "I—I can r-read the assays, Chief Officer. T-Toxicity markers don't change b-between tiers." "Silence!" the officer barked. "She speaks because I asked her to," Vochak cut in, stepping between them. The sheer width of the commander's shoulders blocked Kraynik's view entirely. "Out. Now." The doctor hissed through his teeth, stepped over the shards of glass, and stormed through the blast doors into the corridor. The heavy seals clicked shut behind him, leaving only the dull hum of the building's air cyclers. "Examine the bed," Vochak ordered without turning around. His posture was rigid, vibrating with an unnatural, wire-drawn energy. "Find whatever she left behind. Don't touch the sheets barehanded." Liskra swallowed, her mouth dry as lime. "Y-Yes, Commander." She moved toward the platform bed, its silk bedding tangled and shredded as if two feral beasts had fought for survival upon it. The air smelled of expensive cedar wax, but beneath it lingered that sour, metallic tang—pure scorched ozone. It made the small hairs on her arms stand erect. She pulled a pair of nitrile gloves from her pocket and snapped them onto her hands. Crouching near the left corner of the bed frame, she noticed a faint scuff mark on the baseboard. Someone had kicked it with the heel of a heavy boot. Liskra leaned down, sliding her gloved hand beneath the low clearance of the carved wooden skirt. Her knuckles brushed against cold brass. She pulled it out: an analog blood-sampler, obsolete and brutal, designed for clandestine marrow extractions. A spring-loaded glass vial was seated inside its barrel, its interior lined with coagulant rings. Her palm grazed the release lever, and the world fractured. *Skin against skin, burning hot like steam pipes. A rough hand pinned her wrist against a bolster, but she stayed quiet. She smiled against his collar, tasting salt and ash. 'Be still, my furious dog,' she had whispered into the dark, her voice dripping with venomous amusement. 'You won't sleep, but neither will you rot.' Her thumb had depressed the lever on the very same brass cylinder, driving the needle deep into the vein beneath his collarbone while he shuddered beneath her.* Liskra gasped, snapping her hand back. The brass tube clattered against the parquet floor. "What is that?" Vochak's voice struck her like an iron bar. Before she could reply, a high-pitched whine rose from the ceiling vents. The soft hum of oxygen was instantly replaced by a violent hiss. An oily, ochre vapor billowed from the grates, heavy as wet sand, smelling of sulfur and rotting slate—unfiltered exterior smog, laden with caustic particulate. "The scrubbers failed," Liskra stammered, coughing as the air burned her nostrils. "It's a p-purge bypass!" "Sabotage," Vochak snarled. He avoided the main blast door; the emergency locks had already slammed shut, sirens blaring red across the walls. Vochak lunged across the bed, scooped the brass cylinder off the floor with one claw-like hand, and grabbed Liskra by the scruff of her tunic with the other. He hoisted her bodily off her feet as the yellow cloud swallowed the room. Her lungs burned. She choked on the grit, but Vochak moved with terrifying speed, kicking open a narrow steel hatch recessed into the dressing room wall—an emergency maintenance airlock. He threw her inside, tumbled in after her, and slammed the manual lever down. The hatch sealed with a resounding thud. The yellow fog pressed harmlessly against the thick viewing pane, swirling like angry mud. Inside, the airlock was barely three feet wide. Total darkness enveloped them, save for the faint green glow of a backup pressure valve. Vochak was pressed flush against her, his chest heaving like a bellows, his ragged breath washing hot over her cheek. In the cramped space, there was nowhere to pull back. She felt the heavy, frantic thump of his ribcage, an unnatural, pounding arrhythmia that shook his entire frame. His hand gripped her shoulder, the pressure digging through the fabric of her coat until it bruised. "She was here," he whispered into her ear. His voice was cracked, shivering with three straight weeks of enforced wakefulness. "I can smell her on this glass tube. I smell her on the sheets. And I smell her on you." Liskra went rigid against the metal wall. She pressed her spine hard against the cold steel bulkhead. "C-Commander, please. You're d-deprived. Your mind is creating associations because of the oxygen debt." "She robbed me," he muttered, his lips brushing the hair near her temple as he leaned closer, his pupils blown wide and predatory in the faint green light. "And she left something inside my veins. Every time my eyelids droop, it burns like acid. She locked me inside my own skull, Doctor. She told me I would be the vessel. If I find her... I'll strangle her myself. But I have to find her before my heart bursts from the strain." He dropped the brass sampler into her shaking palms. "You have field reagents in your med-kit. Use them. Tell me who synthesized this." Liskra fumbled with the straps of her kit. Her thumbs shook violently, not from shy hesitation now, but from sheer terror. She uncapped a small vial of luminescent reagent—a crude protein-sequencing dye used in the lower wards. With halting movements, she applied three drops to the crust of dried fluid lining the intake needle of the brass cylinder. The fluid bubbled, releasing a tiny, sharp wisp of green light. A faint sequence of numeric bands appeared across the glass barrel, burned into the cylinder by the proprietary bio-printer that had manufactured it. Liskra leaned in to read the glowing serial numbers, her eyes straining in the dark. *Batch 09-K. Synthesizer ID: 44-L-VA.* It was her own personal identifier from the sanatorium's subterranean archives. The woman who had poisoned the most dangerous officer in the city, the saboteur who had turned him into a sleepless monster to incubate an unlicensed cure, was not a ghost from the wastes. It was her.
